The normal routes (following the road signs) are very nice. But I have two suggestions that might add something:
1. Lucerne - Kandersteg: Hergiswil - Sarnen - Lungern - Brünig.
After descending the (easy) Brünig Pass and near Brienzwiler do not follow the road signs to Interlaken (along the A8) but go to Brienz instead.
In that case you proceed to Interlaken along the north side of lake Brienz. This is a good road and you will go through some lovely villages.
2. Kandersteg - Interlaken: after passing Kandersteg turn right near Mülenen (after petrol station) and follow the signs for Aeschi and Krattigen. You will reach the A8 near Leissigen. This is a beautiful route, with views on lake Thun from a higher altitude.
Wishing you a very nice stay,
